What is Arduino?

    Arduino is microcontroller, so basically a mini computer. It can be program in a modified version of C/C++ straight from a computer. Arduino makes it super simple to make whatever you want, just add on the hardware and write a script and you are good to go. An Arduino has the power to turn things on and off, read sensor values such as the temperature or relative humidity, and can send this data to a computer for us to read.
